FITSP-AModule 4 Gap Analysis
Leadership “…For operational plans development, the combination of threats, vulnerabilities, and impacts must be evaluated in order to identify important trends and decide where effort should be applied to eliminate or reduce threat capabilities; eliminate or reduce vulnerabilities; and assess, coordinate, and deconflict all cyberspace operations…” The National Strategy for Cyberspace Operations Office of the Chairman, Joint Chiefs Of Staff, U.S. Department Of Defense
FITSP-A Exam Objectives • Data Security • Review controls that facilitate the necessary levels of confidentiality of information found within the organization’s information system • Evaluate safeguards in the system that facilitate the necessary levels of integrity of information found within information systems • Audit controls that facilitate the necessary levels of availability of information and information systems • [Security Control] Planning • Audit security plans for organizational information systems that describe the security controls in place or planned for the information systems and the rules of behavior for individuals accessing the information systems • Assess processes to handle the implementation of security plans for organizational information systems that describe the security controls in place or planned for the information systems and the rules of behavior for individuals accessing the information systems

Section A Security Categorization
RMF Step 1Categorize Information System • Security Categorization • Information System Description • Information System Registration
FIPS 199 – Feb. 2004 Federal Information Processing Standards • First step in Security Authorization Process • Security Standards for Categorization of Federal Information & Systems • Requires Solid Inventory of All Systems on Your Networks • Mandated by FISMA • Security Categories Based on Potential Impact
Levels of Potential Impact Impact on organizations, operations, assets, or individuals • Low - Limited adverse effect • Moderate - Serious adverse effect • High - Severe or catastrophic adverse effect Effectiveness reduced Minor damage/loss/harm Financial loss Harm to individuals Loss of life, mission capability
Knowledge Check • Name the 3 tasks of the RMF Categorization step. • Security categories are to be used in conjunction with what other information in assessing the risk to an organization? • What is the first step to assigning impact levels for security categorization? • What are the key words associated with the following impact levels:
1 - Identifying Information Types • OMB’s Business Reference Model • Basis for Identifying Information types • Four Business Areas/ 39 Lines of Business • Mission Based Information Types • Service for Citizens (Purpose of Gov’t) • Mode of Delivery (to Achieve Purpose) • Management & Support Information Types • Support Delivery of Services (Necessary Operational Support) • Management of Government Resources (Resource Management Functions)
day-to-day activities necessary to provide the critical policy, programmatic, and managerial foundation that support Federal government operations
back office support activities enabling the Federal government to operate effectively
3 - Review Provisional Impact, Adjust/Finalize Impact Levels • Review • Adjust (based on special guidance from 800-60)
Guidelines for Adjusting System Categorization • Aggregation • Critical System Functionality • Extenuating Circumstances • Public Information Integrity • Catastrophic Loss of System Availability • Large Supporting and Interconnecting Systems • Critical Infrastructures and Key Resources • Trade Secrets • Overall Information System Impact • Privacy Information
4 - Assign System Security Category • Review for Aggregate Information Types • Identifying High Water Mark Based on Aggregate • Adjust High Water, as Necessary • Assign Overall Information System Impact Level • Document All Security Categorization Determinations and Decisions
Subsection A.1 Special Types of information
Special Types of information • National Security (NS) • Health Information (e-PHI)(Electronic Protected Health Information) • Personally Identifiable Information (PII)
National Security Systems • SP 800-59 Guideline for Identifying an Information System as a National Security System • Involves Intelligence Activities • Involves Cryptologic Activities Related to National Security • Involves Command and Control of Military Forces • Involves Equipment That is Part of a Weapon System • Is Critical to Military or Intelligence Missions • CNSS1253 Security Categorization and Control Selection for National Security Systems • Derives Authority from National Security Directive 42 , and • CNSS Policy No. 22 (IARMP) • Companion Document to NIST SP 800-53
Distinctions of CNSS 1253 • High Water Mark Not Used • Categorizations Tailored Through Risk-based Adjustment • Supplements Use of Impact-level Determinations with Control Profiles • Member Organizations Practice Reciprocity with Respect to System Certification
SP 800-66r1 Introductory Resource Guide for Implementing the Health Insurance Portability and Accountability Act (HIPAA) Security Rule • Applicable to Covered Entities • Covered Healthcare Providers • Health Plans • Healthcare Clearinghouses • Medicare Prescription Drug Card Sponsors • Six Sections of the HIPAA Security Rule • Security standards • Administrative Safeguards • Physical Safeguards • Technical Safeguards • Organizational Requirements • Policies and Procedures and Documentation Requirements
Security Rule Standards and Implementation Specifications Addressable Required
Categorizing Privacy Information • New Guidance – SP800-122 • Organizations should identify all PII residing in their environment • Organizations should minimize the use, collection, and retention of PII to what is strictly necessary to accomplish their business purpose and mission • Organizations should categorize their PII by the PII confidentiality impact level • Each organization should decide which factors it will use for determining impact levels and then create and implement the appropriate policy, procedures, and controls.
Factors for Categorizing PII • Ability to Identify • Quantity of PII • Data Field Sensitivity • Context of Use • Obligations to Protect Confidentiality • Access to and Location of PII
Security Controls for PII • Creating Policies and Procedures • Conducting Training • De-Identifying PII • Using Access Enforcement • Implementing Access Control for Mobile Devices • Providing Transmission Confidentiality • Auditing Events
Knowledge Check • What is the basis for defining information types? • The BRM describes [how many] business areas containing [how many] FEA lines of business. • Which NIST document lists information types, and their associated provisional impact level? • List reasons for adjusting a system’s provisional impact level. • Which NIST Special Publication provides guidance for protecting PII?
